UltraTech 5234 Ultra-Archaea Boom, 6" Length x 4" Width x 1" Height (Box of 6) Ultra-Archaea are housed in a bentonite clay powder that provides the slightly moist environment needed for them to live. Two sizes of shakers available for application on smaller spills or contained areas. Resealable/water-proof containers keep microbes dry/dormant until they are needed. 4 oz. water soluble packets can be thrown into oil/water separators, catch basins, grease traps, and other areas to facilitate oil and grease removal. Small size, big results  no measuring, scooping or spreading. Simply place the entire packet into the area that needs to be cleaned. The water-soluble packet will dissolve and allow the Ultra-Archaea to spread throughout the area. Bulk bags (25 lbs.) are available for large spills, open water applications or frequent use areas. Keep on hand for refilling Shakers or other smaller containers or for large, unexpected spills. Specially-treated polyethylene foam used in Ultra-Archaea Booms allows it to float on the waters surface while also absorbing oil. Microbe tablets (6) are inserted into slits in the foam sleeves  extended water contact causes the tablets to slowly dissolve, releasing the microbes into the water. Booms can be dropped in, or tied off in catch basins (lanyards included), oil/ water separators or other areas where oily water can collect. Dimensions:6&#034; x 4&#034; x 1&#034; (152mm x 102mm x 25mm).
